Queens Gambit Declined Marshall Defense Beginner Puzzle (Rated 869): Win Material — Queen's Gambit Declined

This classical chess puzzle comes from the Queen's Gambit Declined and shows how active piece play can outweigh static material. White appears to have extra material, but Black’s pieces are coordinated around the white queen and king. The key idea is a forcing tactical sequence that begins with a check and creates a fork-like pressure on the queen and king. In the middlegame, these dynamic threats can turn a seemingly worse position into a decisive material gain.
